4 Claims. (01. 292-246) The present invention relates to means for locking window sashes in a closed position and in various open positions and forms a divisional of my pending application Serial No. 255,570, filed February 10, 1939, now issued Patent No. 2,271,930, February '3, 1942, for Window sash and locking device.

My invention relates to convenient means for locking the sash in a closed position and for breaking it loose from the closed position and for looking it in various open positions having means for limiting the extreme open position of the sash.

An object of the present invention is to provide an overhanging arm which is curved and positioned on a radius with the upper sash hinge and having on its outer end a stop for limiting the extreme open position of the upper sash and forming a, holding means for the lower sash when open.

An object of my invention is to provide means whereby when the sash is closed by pulling a depending arm away from the upper sash, the sash willbe forced open slightly and whereby when the sash is open to a predetermined position, the

depending arm may be moved back into its locked position so the sash will be locked into position.

A further object of the present invention is to provide a lower sash which is hinged near the hinge of the upper sash and having about the same length whereby when swung open, it may be brought in contact with the end of the overhanging means, the overhanging means being provided with a latch for securing the lower sash in this open position.

Another object of my invention is to provide a lower sash and a sill therefor having means whereby when the lower sash is closed, it may be yieldingly locked in its closed position and having means attached to the sill whereby a dead air space is provided having a drain outlet whereby any water that may find its way under the sash will flow from the dead air space.

i To these and other useful ends, my invention resides in parts, combinations thereof, or their equivalents, and mode of operation, as hereinafter described and claimed and shown in the accompanying drawings in which:

Fig. 1 is a rear or inside elevation of the preferred form of my invention.

Fig. 2 is a section of the device, as shown in Figure 1, taken on line 2-2 of Figure 1.

Fig. 3 is an enlarged fractional vertical section of the upper sash, illustrating the locking devices as viewed from line 2 of Figure 1.

Fig. 4 is an enlarged fractional vertical section taken through the check rails and illustrating the right hand sash hinge.

Fig. 5 is an enlarged fractional vertical sill section including a fraction of the bottom sash, its locking device and the sealing means and condensation drain.

Fig. 6 is an enlarged horizontal section of the upper and lower sash hinges taken on line 6-6 of Figure 4.

Fig. 7 is an inside elevational view of the right hand sash hinge.

- Fig. 8 is a fractional elevation of the lower sash, sill and side jambs as viewed from the outside.

Fig. 9 is a modification of the sash hinges taken as in Figure 4.

As thus illustrated, I have shown the preferred embodiment of my invention wherein the upper sash is, in its entirety, designated by reference character A, the lower sash being similarly designated by reference character 13. The main frame is, in its entirety designated by reference character C.

Member A, as illustrated, comprises a bottom L-shaped check rail l0, side T irons H-H and a top T iron rail l2. Mullions l3 and M are secured to rails II and members it! and I2, as illustrated, when a six panel frame is desired.

Member B comprises an L iron check rail l5, a bottom T iron rail l6, and T iron side rails ll-ll having mullions l3 and I4 secured thereto, as in member A.

All of the parts thus described form members A and B and are preferably electric welded together thus forming reasonably sized sashes having great rigidity and strength but being light and easily handled.

The panes of glass 18, it will be noted, are exact replicas and preferably seated in putty and held into position by suitably shaped brass L strips is, see Figure 5.

Member C comprises a sill 25, the top surface of which tapers downwardly for its entire width (see Figure 2). The side jambs 26 and 21 and top header 23 are formed into five members a, b, c, d and e (see Figure 3). Member a is the inside plate, e forms a seat or rest for the outside lip of members H, I2 and H (see Figures 3 and 6), and member 0 forms a seat for the outer edge of the transverse portion of members i I, I2 and I1.

I provide a 2 iron 29'which is secured to member 25 as illustrated in Figure 5, the outer edge being flush with the outer edge of member I6 and the end being in juxtaposition to the lower edge of this member.

An L shaped strip 3% is secured to member 28 so as to form a rest for the outer edge of the transverse portion of member it (see Figure Member 36 is provided with a number of apertures 3| and member 29 is provided with a number of apertures 32. Apertures 3i and 32 are staggered so as to prevent direct air passage into the building. These apertures cooperate with member to form a drain to the outside for any condensate which may flow down from the inside of the windows. These apertures are small but large enough to provide suitable drainage for the purpose described It will be noted by referring to Figure 4, that I check rails l0 and i5 are in contact one with the other. In Figures 4., 6 and 7, I illustrate my preferred form of hinge wherein plates 35 are secured to members I) of the side rails 2.6 and 2'1. These plates extend inwardly, as illustrated.

I provide an aperture 36 which extends through members B and 35. I also provide an aperture 3? in the outer end of member 35. A tube 38 is secured to member HI preferably by electric welding as at 39. A bracket 46 is secured to the upper and outer corners of member B preferably by electric welding as at il. Member All is provided with an aperture 42.

A washer 43 is provided between members 35 and and the hinged connection between these members is formed by means of a rivet M which is held into position preferably by means of a cotter pin 45. A rivet 46 forms the hinge'connection between members A, 35 and b. This rivet is held into position by means of a cotter pin 7. Thus it will be seen that members A and B are hingedly mounted on the side jambs of the frame and at the vertical center thereof whereby members A and B may be replicas except in the small attachments and the hinges just referred to. Thus convenience in manufacturing will be provided.

I have described the preferred form of sash hinges. In Figure 9 I illustrate a modification wherein members iii and iii are each provided with plates 58 which are preferably secured thereto by electric welding. Plates 39 are secured to member b of the side jambs similar to mem ber 35. Suitable apertures are provided in members 48 and 49 for the reception of rivets 50-58 which are held into position similar to the rivets in the other figures. Thus it will be seen that a substantial hinge arrangement will be provided in another way than that shown in Figures 4, 6 and 7.

I provide an L-shaped plate 55 which is suitably secured to member H], the depending portion being shaped as illustrated in Figur 4. Thus, clearly, when sashes A or B are opened, the space left between members H3 and I5 will be protected against rain and snow. I provide preferably two U-shaped brackets 56 on the inner surfaces of member 55 (see' Figures 1 and 5). A hand locking device 5? is hingedly mounted on sill 25 by means of a bolt 58 and is provided with a cam surface 59 which is adapted to engage the outer surface of brackets 593 and tightly hold the bottom of sash B in its closed position when lever 5'5 is turned clockwise, as indicated by curvilinear arrow in Figure 1. Members 56, it will be noted, will yieldingly contact member 59 for a purpose too obvious to require further description.

I provide a fastening and adjusting device for the free end of member A as follows:

A U-shaped bracket 69 is secured to member 28 as illustrated, having depending portions El. A curved bracket 62 is secured to member 69 and has upwardly extending projections 63 and an upwardly extending portion 64 at its free end having hinged thereon a wire loop 55. When member B is open wide, loop 55 is hooked over member l8, as illustrated by dotted lines in Figure 3, thus to firmly hold member B in its wide open position.

Brackets (it are secured to members iii in spaced relation (see Figure 1) having apertures for the reception of the short horizontal portion of loop 67 as at 6858. A crank portion 69 of loop 61 is adapted to tightly contact depending member 6! when the sash is closed and loop 63 is in the position shown in Figure 3 in which position it is held by means of a spring latch 18.

Thus it will be seen that by pulling the depending end of loop 6? away from the sash, member d9 will contact member A of top headerZB and act to open sash A or break it loose from its contact with the frame if it happens to be frozen. By moving member Bl far enough, member 69 will be moved rearward and downward far enough to pass under member 61 so that the window can be further opened. If, however, it is desired to lock the window in a partially open position, say at the first projection 53 on member 52, the loop may be moved back into its engaged position with spring latch 75 so the crank portion '75 will engage member 62 between two of the projections 63.

It will be seen that sash A may be locked into various positions along the length of member 62. Or, for example, in its furtherest open position as indicated by dotted lines in Figure 3. Thus clearly, when loop 6"! is manipulated, the sash may be closed, broken loose, or adjusted to any desired position within the range of member 62, and that when sash A is open, any passage of air into the closure through the opening will be diverted toward the ceiling thus to prevent direct drafts from contacting the animals or birds within the inclosure. If, however, there is no harmful movement of air on the outside of the building, the lower sash may be opened and hooked in its open position by means of member as.

Clearly, I have provided a simple, easily manufactured and efiicient device which provides a double seal when the sashes are closed. It will be understood that I have illustrated and described my preferred design and that many minor detail changes may be made without departing from the spirit and scope of the present invention, as recited in the appended claims,

Having thus shown and described my invention, I claim:

1. In a device of the class described, comprising a frame and a sash hinged at its bottom to the frame, in combination, an elongated inwardly extending bar secured at its outward end to the upper header of the frame, a downwardly extending loop having widely spaced side bars which are hingedly mounted on the top rail of the sash, brackets secured to the top frame header adjacent said loop hinges and having downwardly extending lips which are spaced inwardly a short distance from the header, upwardly extending cranks securedto the upper end of said loops side bars adjacent their hinges and having a central inwardly extending crank connected therebetween which is positioned over the top of said elongated bar, means whereby said central crank will engage the upper side of said elongated bar when said loop is moved to its outward position, said first cranks adapted to engage the outer edges of said lips and force the sash into its closed position when the loop is moved to its outward position and means whereby the sash will be moved from said frame when the loop is moved inwardly a short distance and whereby a further inward movement of the loop will permit said first cranks to pass under said lips.

2. A device as recited in claim 1 including; spaced projections on the upper side of said inwardly extending bar and means whereby said sash will be locked in various open positions when the loop is moved to its outward position.

3. A device as recited in claim 1 including; means on said sash at the bottom of said loop adapted to hold the loop in its forward position.

4. A device as recited in claim 1 including; said inwardly extending bar being fiat in cross section with its wide sides positioned horizontally transversely and being curved substantially on a radius with said sash hinge and adapted to rest on the sash against the pressure of said central crank and having a stop on its inner end adapted to limit the inner position of the sash.
